GAIN • The function depends on the value of Pr30.
Connection
to COM-
0 Open Velocity loop: PI operation
Close Velocity loop: P operation
1 Open • 1st gain selected (Pr10, 11, 12, 13 and 14)
Close • 2nd gain selected (Pr18, 19, 1A, 1B, 1C)
• No.2 Gain change Funcutions See Protective Adjustments on page 62.
A-CLR • If the COM- connection is kept closed for more than
120 ms, the alarm status will be cleared.
• For details, see Protective Functions on page
64.
Symbol
PULS1 • This is the input terminal for command pulses. The driver receives
this signal by a high-speed photo coupler.
PULS2 • The input impedance of PULSE and SIGN signals is 220É∂.
• Command pulses can be input in three different ways. Use
SIGN1 Pr42 to select one of the following.
1) Quadrature (A and B) input
SIGN2 2) CW (PULSE)/CCW (SIGN) pulse input
3) Command pulse (PULS)/Sign (SIGN) input
DIV • With COM- closed, the numerator of the command scalar is
changed from the value stored in Pr46 (Numerator of 1st Com-
mand Scalar) to the value stored in Pr47 (Numerator of 2nd
Command Scalar).
< Note >
Don't enter command pulses 10 ms after or be-
fore switching.
BATT + • Connect a backup battery for absolute encoder
BATT - (pole-sensitive !).
• If the battery is connected directly to the driver, it is not neces-
sary to connect a battery to this terminal.
